From: Gregory Haskins Date: Fri, 25 Jan 2008 20:08:10 +0000 (+0100) Subject: sched: RT balancing: include current CPU X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2de0b4639f4b1b6bfe31f795e5855f041f177170;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git sched: RT balancing: include current CPU It doesn't hurt if we allow the current CPU to be included in the search. We will just simply skip it later if the current CPU turns out to be the lowest. We will use this later in the series Signed-off-by: Gregory Haskins Signed-off-by: Steven Rostedt Signed-off-by: Ingo Molnar --- diff --git a/kernel/sched_rt.c b/kernel/sched_rt.c index ffd02720b58f..95f36f61ae1d 100644 --- a/kernel/sched_rt.c +++ b/kernel/sched_rt.c @@ -277,9 +277,6 @@ static int find_lowest_rq(struct task_struct *task) for_each_cpu_mask(cpu, *cpu_mask) { struct rq *rq = cpu_rq(cpu); - if (cpu == rq->cpu) - continue; - /* We look for lowest RT prio or non-rt CPU */ if (rq->rt.highest_prio >= MAX_RT_PRIO) { lowest_rq = rq; @@ -307,7 +304,7 @@ static struct rq *find_lock_lowest_rq(struct task_struct *task, for (tries = 0; tries < RT_MAX_TRIES; tries++) { cpu = find_lowest_rq(task); - if (cpu == -1) + if ((cpu == -1) || (cpu == rq->cpu)) break; lowest_rq = cpu_rq(cpu);
